Re: "I'm really not interested in explaining the physics"
There's nothing crazy about asking hard questions, mate. There's lots crazy about denying the answers when those answers come in the form of informed opinions from the overwhelming number of experts involved.
There's lots crazy about asking questions that have already been debunked, and of then returning to those questions after having had things explained to you as though by re-asking those same questions you are somehow proving something.
Look: long story short? The official explanations for how the thing came down make sense. A combination of warm (and hence deformable) truss joints, damage to the core supports and impulse shock absolutely could (and evidently did) cause those towers to collapse.
As for the lady in the hole, that's one I actually can explain. Here goes: if you look at all the simulations, the very bottom of that hole (where the lady is) is on a floor that was only barely damaged by the plane impact. A part of a wingtip hit it. A goodly chunk of one side (I can't remember which) was left undamaged by the impact and likely still had most of a roof over it.
Now, that roof would have been crumbling and deforming and the core of the building where the stairs were would have been a hellish inferno. Smoke and heat would drive what few survivors there were to the edges where, presto, a hole in the building appears.
That isn't magic. Studying the images of where the lady is as well as the simulations of the impact can show you a viable path for her to have made her way there, even as her world literally burned around her.
But that right there is my point. That's one little thing amongst hundreds that the truthers hold up as each somehow independently proving that the whole thing was a lie. You could spend a lifetime whacking those moles but not only will they only find new ones to feed their paranoia...they'll go back to the ones you've already debunked and claim that you were lying/it was somehow impossible/minor tidbit #58709438 means that your debunking is false thus the original assumption must be true...
...it doesn't end. The fact that you keep returning to these items and that you are basically repeating the truther dialogue item for item, rejecting any and all formal debunking work done by experts means that I could waste my life on this and never get anywhere.
It has become more than simply a matter of intellectual curiosity. It has become religion. It is part of your core identity and how you relate to the world.
I could no more convince you of the truth of what occurred to those towers than you could convince me that we should tear up the Universal Declaration of Human Rights. For me, the UDHR is a foundational belief item from which all other things I hold to be true - the structure of my ethics and how I judge right and wrong - flow.
For you, the idea of a conspiracy surrounding 9/11 has become the exact same thing. A foundational element of your personality. You can't accept that the truth of the physical events are more or less as told to us because that would tear up your entire world view. It would utterly shatter your belief system to accept such a thing.
Now the problem is that between the two items, we call one normal and the other crazy.
A human without an ethical center inevitably succumbs to an ever greater spiral of existential despair. So most people cling to religion. Others find their ethical center in various other documents, like the UDHR, law, the Hippocratic oath, etc.
But we need something upon which to build a framework of reference by which to judge the world around us. Our minds aren't evolved to function in a world lacking ethical referents. If I didn't believe in something like the UDHR as a foundation for right and wrong, I would be mad.
But believing in a conspiracy, against all evidence and expert opinion...that is mad. Am I peckerheaded asshole for actually having the gall to say so? You know what...I probably am. I was raised by shrinks, so talking about mental health issues openly and publicly and is a pretty normal part of my childhood. I realize it violates social conventions.
But I also know that mild paranoid schizophrenia is treatable. What's more, it's nothing to be ashamed of. It's just a state of being. I have ADHD. It's on the autism spectrum, basically the exact opposite of mild paranoid schizophrenia. The primary ailment is massively poor impulse control.
But here's the thing, sir. You can prove me wrong. Sit down with a qualified psychiatrist and discuss all this with them. If they prescribe you some drugs, take them for the full length of the dosage period. If they prescribe CBT (or a combination of CBT and drugs) go to all the sessions.
If I'm wrong, then a full course of treatment won't affect the steadfastness of your beliefs at all. If, however, I am right, then getting help will cause the importance of those beliefs to your identity to evaporate, and you'll be able to consider the incident as the rest of us are able to.
And then you know. You have a condition. You were born that way. There are drugs and/or CBT that can level it out..cool. It's just a state of being. There is no dishonour in it any more than being born blind...or "normal".
But by refusing to believe that we might have a problem...that's where we move into shameful choices. We shame ourselves and those around us by having the arrogance to presume that we are somehow able to see things that much clearer than everyone else. That we are somehow "normal" while everyone else is crazy.
Statistically, that's really, really unlikely.
So yeah, I'm not going to argue each and every little point until the end of time. I probably could, but to be perfectly honest with you, I would go stark raving looney-toons from the repetition long before you conceded even a single point.
If I'm particularly lucky, however, I will have planted a seed of doubt in your mind that maybe - just maybe - your quality of life could improve if you sought psychiatric help. And maybe - just maybe - one day you will. I honestly believe that if you did so, your life would improve. And even if you (and others) hate me for being an arrogant asshat, if one day I can make your life (or the life of someone else who reads this) better by convincing them to seek help...it's all been worth it.
Never stop asking hard questions. But also don't fear the the answers may be mundane.
